Circuit Library

This module provides a library of BosonicGate implementations.


State preparation

Column 1
Column 2
InitializeModes(occupation)Prepares a bosonic Fock state.

Passive linear optics

A number-conserving transformation of the mode operators, generated by bi†bjb^\dagger_i b_j. Beamsplitters and phase shifters are the two-mode and single-mode special cases, and together they generate any U(M)U(M).

Column 1
Column 2
ModeRotation(rotation_unitary, *[, synthesis])Implements a passive linear-optical mode transformation.

Time evolution

Column 1
Column 2
Evolution(num_modes, operator[, time, ...])Implements the time evolution of a bosonic operator.

Synthesis methods

How an Evolution gate gets decomposed in bosonic space is configurable through its synthesis argument. The available methods live in the synthesis module.
